Douglas Hofstadter: The Nature of Categories and Concepts
Stanford Symbolic Systems Distinguished Speaker Lecture Thursday, March 6, 2013.
Douglas Hofstadter, College of Arts and Sciences Distinguished Professor of Cognitive Science and Comparative Literature. Indiana University.
What is a quintessential category? Bird, perhaps? Or maybe chair? And what is a quintessential concept? Two? Number? Prime number?
I’m not trying to put words into your mouth — I’m just trying to get you to ask yourself these questions. Also, I wonder if by any chance you thought that these are really exactly the same question, in which case you might have wondered why I asked you the same question twice.
Or did you perhaps think something along these lines: \.
Neuron-targeted gene therapy rescues multiple phenotypes of STXBP1-related disorders in mice and is well tolerated in nonhuman primates
Aeran and colleagues present research on targeted gene therapy vector engineering and pre-clinical testing of neuron-targeted AAV9-based constructs for STXBP1-related neurodevelopmental and epileptic encephalopathies. Candidate vectors designed to target specific neuronal types and detarget tissues associated with toxicity produced robust phenotypic reversal in Stxbp1 +/− mice and were well tolerated in monkeys.

Life Summit — Tomorrow.bio
Many people want to live longer than what is currently possible, but medical technology is not progressing fast enough. At Tomorrow Biostasis, we use the latest cryopreservation technology to medically preserve and protect you for as long as it is needed. When medical technology has solved the life extension and aging problems, you will be reanimated to enjoy an extended life.
On the YouTube channel of Tomorrow Biostasis you can find more information about the concepts of cryopreservation, cryonics, biostasis, vitrification, human revival, and more. We also provide you with practical information about signing up with Tomorrow Biostasis. Get ready to get an insight into the fascinating world of cryopreservation!

New technique cools high-performance chips from the inside out
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a technique to carve microscopic liquid-cooling channels directly inside silicon semiconductor chips.
Interestingly, the computer architecture slashed the energy required for cooling by pumping ordinary, room-temperature water straight through the chip’s internal structure.
“As the performance of AI semiconductors and advanced electronic packaging becomes increasingly limited by heat, we expect this technology to serve as a foundational cooling solution for future high-performance computing systems,” said Professor Sung Jin Kim.
[News] World’s Smallest Semiconductor Nanotube Achieved at 1 Nanometer
A research team led by the The University of Tokyo has fabricated the world’s smallest semiconductor nanotube, according to a study published in the latest issue of Science. Using boron nitride (BN) nanotubes as a template, the researchers successfully synthesized single-walled molybdenum disulfide (MoS₂) nanotubes with a diameter of just 1 nanometer—roughly one hundred-thousandth the width of a human hair.
The achievement not only validates theoretical predictions about the electronic properties of ultrafine materials made decades ago, but also opens new possibilities for the development of next-generation miniaturized electronic devices.
Carbon nanotubes have long attracted attention for their exceptional mechanical and electrical properties. However, slight variations in their atomic structure can significantly alter their conductivity, posing challenges for transistor applications. In contrast, MoS₂ is an intrinsically semiconducting material with promising potential for semiconductor electronics, high-sensitivity sensing, and quantum-scale physics research. Yet producing ultrathin, structurally controlled MoS₂ nanotubes has remained a major challenge, as stability and fabrication complexity increase dramatically as nanotube diameters shrink.
